Summary: In this study, the ageing mechanisms and moisture absorption behavior of epoxy resins and carbon fiber composites were investigated. The results showed that the ageing process primarily involved physical adsorption of water, which did not significantly affect the chemical structure and microstructure. The absorbed water caused micro-cracks at the fiber-resin interface, weakening the interfacial strength and reducing the mechanical properties of the composites.

Summary: The addition of graphene oxide (GO) and p-Phenylenediamine functionalized graphene oxide (fGO) to tetra-functional epoxy resulted in lower activation energy for curing behavior, indicating a more efficient curing process compared to neat epoxy. This was attributed to the amine groups on the surface of the filler, acting as a secondary hardener that triggered the epoxy ring opening reaction.

Summary: Carbon fibre reinforced polymer composites have superior properties and are increasingly used in industries like aerospace. Structural health monitoring is necessary due to their complex failure mechanisms. Magnetostrictive materials have been effective in damage detection but need improvement in spatial sensitivity. It is important to demonstrate ease of fabrication, damage detectability, and maintain a good weight-to-cost trade-off.

Summary: Ceramic/polymer dielectric functional composites, specifically the (Ba0.6Sr0.4)TiO3/PEEK (BST/PEEK) composites, were prepared with high frequency stability of the dielectric constant and low dielectric loss via cold-pressing sintering. The optimal properties of the BST/PEEK composites were achieved at a BST concentration of 40 vol% and sintered at 360°C for 1 hour, showing a permittivity of 23, a loss of 0.0065, F(x) <5%, and a dielectric tunability of 11.9%. The study provides insight for developing new composites with low loss and high frequency stability.

Summary: A facile strategy for effectively constructing in-plane and through-plane thermal conduction paths in polyimide (PI) and its flexible copper clad laminates (FCCLs) was reported by incorporation of hexagonal boron nitride (h-BN) in a controlled manner. The specific sea-island architecture allowed the preparation of highly thermally conductive flexible PI film and its FCCLs at relatively lower total boron nitride loading. The results of the current work may open a new avenue for promoting the practical application of thermally conductive PI based FCCLs.

Summary: This study investigates the applicability of post-weld treatment techniques for large offshore structures, using empirical and theoretical analysis. The results show that ultrasonic impact treatment and pneumatic impact treatment can improve fatigue life but did not reach the expected level. These findings provide evidence for implementing post-weld treatment in offshore construction, but also raise the discussion of redesigning structures for cost-efficient automation.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
